Oil and gas production from the pyrolytic transformation of recycled plastic waste: An integral study by polymer families
Open accessAbstract
Different plastics recovered from a local urban solid waste plant were collected before landfilling, separated, and classified by families, i.e. polyethylene (PE), polypropylene (PP), high impact and expanded polystyrene (HIPS and EPS, respectively), polyethylene terephthalate (PET), and polyvinyl chloride (PVC). A systematic pyrolysis study was carried out to compare the different behavior registered in each plastic type, and an integral analysis of the produced oils and synthetic gas was conducted. In general terms, the oil yield followed the order EPS > PP > PE > HIPS > PET > PVC, reaching maximum values over 500 °C after 1 h of treatment. The oil from HIPS, EPS, PET, and PP was rich in light compounds, i.e., C5-C9 hydrocarbons. Almost 100 % of the oil from HIPS and EPS pyrolysis was aromatic. The aromatic fraction was important in the case of PVC (57 %) and PET (45 %). PE produced an oil with the most varied distribution of compounds but rich in olefins (67 %). The analysis of the non-condensable composition of the gas showed that in all the pyrolysis gases methane was over 50 % (vol.), followed by ethane in importance. CO was produced in the case of PET.

Waste polyvinyl chloride generally results in lower oil yields and fuel quality because it releases corrosive hydrogen chloride gas.
“while PVC releases corrosive hydrogen chloride gas, both of which diminish the yield and heating value of the desired hydrocarbon oil fraction [335-337].”

Waste polyethylene terephthalate generally results in lower oil yields and fuel quality because its oxygen content leads to formation of oxygenated compounds and higher char.
“Waste polyethylene terephthalate (PET) and polyvinyl chloride (PVC) generally result in lower oil yields and fuel quality due to their inherent chemical structures: PET's oxygen content leads to the formation of oxygenated compounds and higher char, while PVC releases corrosive hydrogen chloride gas, both of which diminish the yield and heating value of the desired hydrocarbon oil fraction [335-”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
